Raw Water Supply System Intake Pumping Station

Projects

Westridge constructed the Raw Water Supply System Intake Pumping Station for the City of Saskatoon. The project involved the installation and removal of a 75,000 cu.m. earth coffer dam for an in-river intake structure and pumping station that was built on an existing river spur. A bentonite slurry cut-off wall was installed in the middle of the coffer dam berm with a 100% seal achieved. The scope of work included earthworks for the access roads and build-up of the existing deflection spur, a 10m deep concrete pump station substructure requiring 6,500 cubic meters of concrete, a 30.65m x 20.65m steel and masonry pump station building, and an adjacent concrete valve chamber. Westridge also purchased and installed all of the major pre-selected equipment including the intake screen system, raw water pumps, slide gates, VFD’s and a natural gas generator. Westridge provided value engineering to facilitate cost-saving suggestions, allowing the project to proceed within the original budget constraints.
